<p>Hi<br>
<br>
no, we don't use B2B on OpenSIPS side. Is this the correctway to
do it?<br>
The thing is that I don't know what would be the best way to
implement this with use of RTPengine.<br>
I found very little info available online.<br>
<br>
Call forwards that I manually set in DB (cfu, cfnr, cfb.....like
we were doing on last bootcamp) are working fine.<br>
Only issue is with answered call and then attempting to transfer
it.<br>

<br>
Do you use B2B on the OpenSIPS side ? Which entity is actually
performing the transfer ?<br>
<br>

<div class="moz-forward-container">Hi<br>
<p> <br>
I am using opensips 3.2 with rtpengine on same server and
trying to achieve attended call transfer.<br>
<br>
In theory, I'm trying to do: <br>
1. A calls B...and B answers<br>
2. B puts A on hold (MOH is played from RTPengine)<br>
3. B calls C...and C answers<br>
<br>
Now the funny part:<br>
B tries to transfer A to C and sends REFER to opensips<br>
In opensips I responds with 202 Accepted and B gets
disconnected.<br>
<br>
However A and C don't get connected together<br>
A still receives MOH and C has no voice<br>
<br>
We have another installation of opensips where REFER handles
Freeswitch, and there such type of transfer is working fine.<br>
<br>
Can someone help me how to handle such call behaviour in
opensips with RTPengine?</p>
<p><br>
relevant part of code:<br>

if(is_method("REFER")) {<br>
xlog("[IN_DIALOG] [$rm] Transfer from $fu to $tu");<br>
send_reply(202, "Accepted");<br>
<br>
#what next?<br>
<br>
exit;<br>
}</font><br>
